Troubleshooting, Adjustments, & Service
MOWER DECK LEVELING
Perform these adjustments on a flat level surface.
SIDE-TO-SIDE LEVELING
1. With the mower installed, place the rider on a
smooth, level surface such as a concrete floor. Turn
the front wheels so they are straight.
2. Check for bent blades and replace if necessary.
3. Place the mower cutting height pin in the 4th hole
from the bottom (see insert, Figure 30). Arrange the
outside mower blades so that they are pointing from
side-to-side (Figure 28).
4. Measure the distance between the outside tips of
each blade and the ground (Figures 28 & 29). If there
is more than 1/8” (3mm) difference between the
measurements on each side, proceed to step 5. If the
difference is 1/8” (3mm) or less, proceed to step 6.
5. Use the rear leveling links (B, Figure 30) to adjust the
side-to-side leveling of the deck. Repeat step 4 if
necessary.
FRONT-TO-BACK LEVELING
6. Arrange the blades so they face front-to-back (Figure
31).
7. Measure the distance from the ground to the front tip
of the center blade, and from the ground to rear tips
of left-hand and right-hand blades (Figures 29 & 31).
The front tip of the center blade should be 1/4" (6mm)
higher than rear tips of left-hand and right-hand
blades. If not, proceed with steps 8 - 11.
8. Check the length of the hanging rods. The rear (D,
Figure 30) should be 15” (38,1cm) and is not
adjusted. To adjust the pitch of the mower deck,
adjust the front leveling nuts only.
9. Loosen the front lock nuts (E, Figure 30).
10.Turn the leveling nuts (A, Figure 30) counter-
clockwise to lower the front of mower deck. Turn the
nuts clockwise to raise the front of the mower. Make
adjustments in small increments, trying to keep
tension on both leveling nuts.
11.Tighten the front lock nuts (E).
12.Re-check the blade measurement then repeat steps
7-11 as necessary.
